Tomei Racing Valve Springs for the RB20DET engine are engineered for precision and high performance, ensuring that the camshaft’s movement is accurately transferred to the valves even at high engine speeds. Designed for high-revving engines, these springs are made from top-tier materials like oil-tempered chromium-silicone alloy steel wire, known for its durability in performance applications. Each set is meticulously tested to meet Tomei's high standards for durability, performance, and resistance to wear.

By using cutting-edge surface treatment methods, including nitrogen permeation, Tomei has significantly increased the springs' fatigue limit, making them ideal for high-lift camshafts. This advanced treatment ensures that the springs can withstand the extreme demands of super-high revs—exceeding 10,000 RPM—without the risk of failure. The springs’ unique design suppresses valve jump and bounce, even at elevated engine speeds, providing stability and reliability during performance driving.

Tomei’s meticulous engineering also includes the use of a special process where high-speed steel balls are shot onto the surface of the springs, further enhancing their fatigue resistance. This, along with additional heat treatments, ensures that the springs retain their shape and performance over time without sagging, providing longevity even under continuous stress. The use of oval wire in the design offers greater compression and compatibility with a wide range of camshaft lift settings, whether stock or aftermarket, allowing for optimal performance across various setups.

At Terra Firma Automotive, we offer these Tomei Racing Valve Springs to elevate your RB20DET engine’s capabilities, ensuring long-lasting performance for those who push their engines to the limit.
